SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 444,322, dated January 6, 1891.

Application filed October 9, 1890. $erial No. 367,545. (No model.)

T0 on whom it may concern:

Be it known that I, ROBERT M. SULLY, a citizen of the United States, residing at Petersburg, in the county of Dinwiddie and State of Virginia, have invented new and useful Improvements in SealLocks, of which the following is a specification.

This invention relates to that class of seallocks in which a bolt is arranged to be fastened with the aid of a frangible seal that may also serve as a destination-tag for a railroadcar to which the lock is applied; and the invention consists in the novel features of construction and combination of parts, as hereinafter described and claimed, whereby the said bolt is secured when in looking engagement wit-h a connected seal.

In the annexed drawings, illustrating the invention, Figure, 1 is a view of a portion of a freightcar in side elevation with my improved seal-lock applied thereto and in looking position with a seal-tag attached. Fig. 2 is a perspective of my improved seal-lock as applied to a car, the bolt being shown as secured in looking engagement with an attached seal-tag. Fig. 3 is a sectional elevation of the lock, showing the parts in the position they occupy when the bolt is lowered for attachment of a seal-tag. Fig. 4 is a sectional elevation of the lock, showing the hasp in position and fastened by the bolt, which is secured in'locking engagement with a seal-tag. Fig. 5 is a perspective of a rotary and longitudinally-movable pin provided at one end with an operating-lever, at its other end with a recess to engage a lug on the vertically-movable lock-bolt, and at an intermediate point with a recess to engage a suitable catch in the lockcase, whereby the bolt can be secured when it is in locking engagement with an attached seal. Fig. 6 is a perspective of the bolt. Fig. 7 is a vertical section through the line 00 0c of Fig. 4. Fig. 8 is a similar section through the line 3 y of Fig. 4.

Referring to the drawings, the numeral 1 designates a portion of a car-door, to which is attached a hasp 2, as usual To the doorframe 3, adjacent to the hasp, as shown in Fig. 1, is securely bolted a plate 4:, on the upper portion of which is a lock-case 5, at one end of which is a perforated lug 6, in which the vertically-movable bolt '7 is supported. The plate a is also provided with a staple 8 for engagement with the hasp, and near the lower on d of the plate is a perforated lug 9, by which the lower end of the bolt is surrounded when it is in looking engagement with a seal. In the sides and bottom of this lug 9 are slits 10, which coincide, as usual, with a hooked aper ture 11 at the lower end of the bolt and serve therewith to receive and confine a seal-tag 12 in the usual manner, as shown in Fig. 2.

The vertically-movable bolt 7 is provided on one side of its upper end with a lug 13, adapted to enter a recess 14: in the end and periphery of a rotary longitudinally-n10vable locking-pin l5, Fig.5, that is supported horizontally in the lock-case 5, as shown in Figs. 2, 3, and 4:. This locking-pin 15 is provided outside the lock-case 5 with a lever 16, by which said pin can be operated. In the periphery of the locking-pin 15, intermediate its ends and in line with the end recess 14, is a lateral open-ended recess 17, adapted to engage a vertically-movable catch 18 in the up per part of the lock-case, which catch may be provided with a spring 19 or be carried at the proper time into engagementwith the pin 15 by gravity, as may be preferred.

In order to fasten the door 1 by my improved seal-lock, the bolt 7 is first raised and the hasp 2 carried into engagement with the thrown down, so as to rotate the pin'15 on its longitudinal axis, and thereby disengage the catch 18 from the recess 17 and permit the pin 15 to be drawn outward to the position shown in Fig. 3. The bolt 17 will now be lowered past the inner end of the pin 15 until the bolt-lug 13 comes in contact with the lug 6, by which the bolt is then supported, as shown in Fig. 3, with the lower hooked end of said bolt depending below the slitted lug 9 a sufficient distance to permit the attachment of a seal-tag. bolt 7 should be raised as far as will be permitted by the engagement of the tag 12 in the slits 10 of the lug 9, the lever 16 will then be After the seal is attached the IOO raised to a vertical position to rotate the pin 15 and carry the recess 14 into line with the lug 13 on the bolt, and the pin 15 will next be moved longitudinally inward, so as to engage the recess 1t with the lug 13 and permit the catch 18 to drop into the recess 17, thereby locking the bolt 7, so that itcannot be disturbed without destroying or mutilatin g the seal. It will be observed that while the bolt 7 is in locking engagement with a seal the pin 15 cannot be rocked or rotated, because it is securely held from such movement by the engagementof the bolt-lug 13 in the recess 14, as shown in Fig. 7, while the engagement of the catch 18 in the recess 17, as shown in Figs. 4 and 8, effectually prevents any withdrawal of the pin 15 endwise. To unfasten the lock it is only necessary to break the seal, when the bolt 7 can be at once raised to permit disengagement of the hasp and staple. The inner end of the pin 15 is provided with an annular enlargement 20, that is adapted to serve as a stop in connection with a shoulder 21 in the lock-case 5, and so prevent the entire withdrawal of said pin and its loss by theft or accident. To obviate any danger of losing the bolt 7,it is provided in its rear side with a longitudinal groove 22, as shown in Fig. 6, which is adapted to engage a ston-pin 23, Fig. 7, in the lug (i, and so prevent entire withdrawal of the bolt 7 when it is raised in manipulating the lock.

Instead of employing the tag-seal 12, or in addition thereto, the lock may be sealed by an ordinary lead seal engaged in a well-known manner in openings 24 and 25, formed in the lug (i and bolt 7, as shown in Fig. 4.

From the foregoing description it will be seen that the means for securing the bolt 7 when it is in looking engagement with an attached seal are exceedingly simple in their construction and arrangement and are not liable to get out of order.

What I claim is- 1. In a seal-lock, the combination, with a bolt havinga lug at or near one end, of a retary and longitudinally-movable pin provided at one end with a recess to engage the lugon the bolt, said pin havinga lateral open-ended recess intermediate its ends for engagement with a catch in thelock-case, whereby the bolt is secured and said pin held from rotary and longitudinal movement in the lock-case when the bolt is in locking engagement with a connected seal, substantially as described.

2. In a seal-lock, the combination of a stationary lockcase having a perforated lug at one end, a locking-bolt passed through said log, a rotary and longitudinally-movable locking-pin supportedin thelock-case and adapted to engage the lockingbolt, and a catch located in the lock-case and adapted to be antomatically engaged with and disengaged from said pin, whereby the bolt and pin are seen red from disengagement when the bolt is in locking engagement with a connected seal.

3. In aseal-lock, the combination of the stationary lock-ease 5, the bolt 7, having a lug 13, the rotary and longitudinallymovable locking-pin 15, provided with recesses 14 and 17 and lever-arm 16, and catch 18, substantially as described.

4. In a seal-lock, the combination of the lock-case 5, having in its interior a shoulder 21, the locking-bolt 7, provided with lug 13, the rotary and longitudinally-movable locking-pin 15, provided with recesses 14 and 17, enlarged annular end 20, and lever 16, and the catch 18, substantially as described.

5. Ina seal-lock, the combination of the stationary lock-case 5, the staple S, the perforated lugs 6 and 9, the locking-bolt 7, the retary and longitudinally-movable locking-pin 15, adapted to engage said bolt, and the catch 18, adapted to engage the locking-pin,whereby said bolt and pin are secured from disengagement when the bolt isin locking engagement with a seal, substantially as described. In testimony whereof I have affixed my signature in presence of two witnesses.
